The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...
The Ford EEC or Electronic Engine Control is a series of ECU (or Engine Control Unit) that was designed and built by Ford Motor Company. The first system, EEC I, used processors and components developed by Toshiba in 1973. It began production in 1974, and went into mass production in 1975. It subsequently went through several model iterations.
An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
Control ECU: Haltech Nexus Locked, with Control Wiring Harness; Control Dash: Motec C125 with Data Logging; Exhaust Manifold: Standard GM; Exhaust System: Twin 3inch with X Pipe; Suspension: Pace Innovations Control Rear Adjustable Live Axle, Front standard control arms with front and rear Bilstein Control Coilovers
What made this ECU special was the use of two crank sensors and one cam sensor. The ECU used one crank sensor to count the teeth on the starter ring for its RPM signal, and the other read a pin on the back of the flywheel for TDC reference. This ECU was first seen when the 20V turbo 5-cylinder engine (RR Code) was installed into the Audi Quattro.
One driving force behind this is the increasing adoption of the engine Electronic Control Unit (ECU), which provides one method of controlling exhaust gas emissions within US and European standards. The telematics data is used (via Fleet Telematics Systems ) by Fleet Management Systems to let fleet operators keep track of vehicle and driver ...
It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control Module (BCM), for a total of three separate computers. These automotive computers are generally very reliable.
The typical modern TCU uses signals from engine sensors, automatic transmission sensors and from other electronic controllers to determine when and how to shift. [2] More modern designs share inputs or obtain information from an input to the ECU, whereas older designs often have their own dedicated inputs and sensors on the engine components.
